D. The graph has a positive slope.
Explicación
## Step 1The problem involves understanding the relationship between acceleration and the slope of a velocity-time graph. Acceleration is defined as the rate of change of velocity with respect to time. ## Step 2When an object has a positive acceleration, it means that its velocity is increasing over time. This is represented on a velocity-time graph by a line that slopes upwards. ## Step 3The slope of a line on a velocity-time graph represents the acceleration of the object. Therefore, a positive acceleration corresponds to a positive slope on the graph.
